SHOWER, VALVE..-

rApplication filed October 30, 1926. Serial No. 145,194.

This invention relates to a valve adaptable for use with shower bath ixtures, More particularly, this invention pertains to a valve adapted to be placed within a vertical wall or partition with the valve stem and handlev exposed for convenient operation thereot. Such types of valves are in eiiect embedded in the wall necessitating mutilation thereof in order to remove them. kThey are commonly ot' the compression type wherein cooperating screw threads are employed,V

one on the stem and the other anchored to the body ot the valve. Because oit' wear ot' the threads, the lattermust be renewed from time to time. It is therefore advantageous to have a thread carrying member separable from the valve body and which Vmay be anchored thereto as desired without requiring removal of the body. from the bath lixture assemblage.

The objects or this invention are irst,.to provide a valve body having a ,separable liner carrying a thread; second, to provide a liner of simpliiied structure, lending itself to quick and expeditious assembly and which is durable and economical to manufacture; and third, to provide a valve construction comprising elements subject to wear and so assembled as to be renewable without disturbance of the valve installation.

These objects together with other objects which will appear from the subj oined description are obtained by the embodiment of our invention illustrated in the accompanying drawing, in which: Y

Fig. l is an axial section through acomplete valve, the stem and handle being shown in elevation; Figs. 2 and 3 are sections as seen on the lines'correspondingly numbered in Fig. l; and Fig. L is a perspective view of theliner. y

Referring with more particularity to the drawing, a hollow valve body is indicated by 5. At opposite ends thereof are an inlet and an outlet marked Gand 7 respectively. Dividing the valve .body into inlet and outlet chambers is a partition wall 8, there being an opening for communication of the chambers. Opposite to the opening is a tubular casing extension 9 externally'tbreaded at the outer end. Formed on the wall ot the bore at equallyspaced distances are longitudinally extending ribs, l0, 10a, and 10b. These ribs end short of the outer end of the tubular eX- tension, one oi them being longer than the others, namely 10.

'l`hc openingin the partition is threaded and mounted therein is'. a tubular valve seat extension ll having a valve seat ending short ofthe outer endV oi' extension 9. ln the bore or the scat extension are flattened protuberrib l at its outer end.` T he rib is arranged to f be seat-ed in a corresponding recess in the extension. At the other end of the liner and located at diametrically opposite places are slots 1G. These slots are of such length that eitherwill receive the rib and thereby hold the liner from turning within thel extension 9. Thebore oit the liner has formed on its wall a square threadl for cooperation with a corresponding thread on the valve stem. Mounted over the head oit the liner is a metallic disk 18. A nut cap 19 has apacking` 20 therein so that when the cap is in placeJ on the extension 9 it anchors the liner in position. and forms a leak tight joint.

Extending` through a bore in the cap is the shank 2l of' the valve stem. Mounted upon the end of the shank is a handle 22 `for convenience in turning the stem. At the other end of the shank is a head 9.3 having external threads 24rmeshing with the threads 17 on the liner. Secured to the end of head Qbv means of a screw is a washer 25 arranged to be seated on the end of seat extension l1. The valve. stem is packed by means oi the packing 20.

The parts are shown in assembled condition in Fig. l and as installed. In caseit is is unscrewed permitting the liner to be removed with the vvalve stem. A squareV bar may then be inserted in the seat extension l1 and the latter unserewed and removed, a new one then being inserted. If the threads on the liner are so worn as to need replacement, the liner is unthreaded from the stem. A new liner is then slipped into the eXtensionQ with rib l0 disposed in slot 16.` The stem and cap desired to replace the tubular seat, the cap nut rt the outer end of the eX- are then replaced on the extension. Obviously the removal and replacement may he performed quickly. T he replacement parts are inexpensive, Vand the structure as av unit is durable. l

Although the embodiment of the valve illustrated herein is otthe. type commonly used 'tor shower hath nturesand is suitable for concealment vet the invention is not limited to such embodiment. It may be incorporated i in faucet, globe and angle valves, or any common type of shut-oli.

that We claim is: l. A valve of the class descrihed comprisf ing a casing having an inlet and an outlet separated by a partition having an opening` and a tubular casing extension opposite to said scat extension7 said stein cfdending` vthrough said cap and having' an external thread engaging the thread on said liner..

2. A valve of the class described comprising a casing having an inlet and an outlet separated by a partition'havingan opening and a tubular easing,` extension opposite said opening provided with a longitudinally extending` rib, a seat extension detachaloly mounted in said opening" and disposed in and ending short of said casing extension, a tubular liner disposed in said casing extension having a slot receiving said rih to lock it against rotation7 said liner having,` an internal thread, a cap detachably mounted on said casing extension and engaging said liner to hold the latter in place', and a valve stern having a Washer 'for being seated on the outer endV ot saifl seat extension, said stemv extending throi 1 said capiand havingv an. external thread enh the thread in said liner.

n 3. A valve of the class described comprising a casing liz-wing` an inlet and an outlet separated by a partition provided with an opening' and a tubular casingextension opposite said opening` includingl a plurality oi lon- Aintiulinally extending ribs, one of said rihs extending closer to the end of said extension than'the others to provide a'loeking,` rih7 a tubular Vseat extension detachahly mounted in said opening' and laterally supported in said casing extension by said ri hs, a tubular liner disposed in said casing extension havingl a slot receiving;` said locking rilo to lock against rotation, said liner having an internal thread, a cap detachahly mounted on said extension and engaging said liner to hold the latter in place, and a valve stem having Washer for hein g seated on said seat extension, said stem extending` through said cap and havin an eX- tornal thread engaging' the thread in said liner.

ln Witness that We claim the foregoing We have hereunto subscribed our names this th day oi October, 1926.
